Abstract
The improvement of fuel economy and the reduction of diesel exhaust PM(Particulate Matter) and $NO_X$ have been successfully achieved by supplying diesel engines with emulsified diesel oil. However, combustion analysis of emulsified C-heavy oil is difficult because the combustion characteristics of emulsified C-heavy oil compared to other fuels have a special form. Therefore, these experimental researches have analyzed the combustion characteristics of emulsified C-heavy oil in a chamber with high pressure and temperature. The pressure and the rate of heat releases in a combustion chamber was decreased with increasing the water content and the ignition delay time was increased with increasing the water percent.
디젤기관에 있어서 PM과 NO의 동시저감을 위한 에멀전연료의 적용은 급속도로 발전되어져왔다. 하지만, C중유 에멀젼연료의 연소계측 해석은 다른 연료에 비하여 복잡한 연소형태 때문에 어려움이 많다. 본 연구에서는 높은 압력과 온도의 정적연소실에서 에멀젼 C중유를 분사 연소시켜, 연소해석에 대한 실질적인 근거를 제시한다.
